摘要:
以青海德香高速公路大桥桥墩混凝土为依托,对其沿线主要易溶盐含量进行分析,通过室内模拟实验,配制了7种腐蚀溶液,并设计4种配合比混凝土,通过外观形貌、质量损失率和相对动弹模量3方面研究干湿循环作用下,盐分对混凝土耐久性的影响.结果表明:干湿循环作用下,单一盐类如Na2S04、MgSO4、NaCl溶液对混凝土破坏形式和程度均不相同;在复合盐溶液中,复盐对混凝土的腐蚀损伤效应会发生叠加,而且溶液浓度越大,混凝土腐蚀破坏越严重;掺加水泥基自愈合材料、粉煤灰能够提高混凝土抗盐蚀破坏能力.
Abstract:
Based on the pier concrete of Qinghai Dexiang Expressway Bridge, the main soluble salt content along the line was analyzed. Through indoor simulation experiments, 7 kinds of corrosion solutions were prepared, and 4 kinds of mix ratio concrete were designed. The effect of salt on the durability of concrete under the action of dry-wet cycle was studied from the aspects of rate and relative elastic modulus. The results show that under the action of dry-wet cycle, single salts such as Na2S04, MgSO4, and NaCl solution have different damage forms and degrees to concrete. The same; in the compound salt solution, the corrosion damage effect of the compound salt on concrete will be superimposed, and the greater the concentration of the solution, the more serious the corrosion damage of concrete; the addition of cement-based self-healing materials and fly ash can improve the resistance of concrete to salt corrosion. destructive ability.
